Improving Turfgrass Through Research
Tall Fescue Strategies
• High turf quality, rapid establishment
• Rhizomes - Advertise and promote XRE
• Higher percentage of plants with rhizomes
• More rapid rhizome production
• Verification of rhizomes in mown turf
• Brown patch
• Screening at multiple sites - remove survivors
• Screening progeny from drought / rhizome work
• Drought tolerance and recovery - 3 cycles GA
• Salt tolerance

Improving Turfgrass Through Research
Turf-type Tall Fescue
• Weaknesses
– Bunch-type growth
– Speed of repair slow
– Rhizomes in new varieties may help
– Need more winter-active growth
– Brown patch susceptibility - in enclosed shade can severely damage
– Old cultivars lacked density and texture, new cultivars finer textured, darker green, higher density
![Page 12: Improving Turfgrass Through Research Seed Research of Oregon Turf-Type Tall Fescues John Patton](https://reader036.vdocuments.net/reader036/viewer/2022062515/56649cf65503460f949c571a/html5/thumbnails/12.jpg)
Improving Turfgrass Through Research
Turf-type Tall Fescue
• How to use
• Best results when blended with Kentucky bluegrass - 85 to 90% Tall fescue
• Blending with Texas x Kentucky hybrids may be useful in stress sites
• Brown patch reduced in blends

Tall Fescue
• Advantages: (New Varieties– Dark green color– Heat and wear– Extensive root system– Good density– Good establishment– Good disease resistance
• Disadvantages–Low shoot density–Low temperature injury–Weak sod forming–Thinning stands leads to clumping
